Method and system for scanning television systems using a first quick scan and a second slower scan

ABSTRACT

A method of scanning television channels at initial setup. The method includes at a first power mode, automatically scanning for channels using a first scanning setup procedure during which the television is unusable by a user. The first power mode is when the television is at a full power mode. The detected channels are automatically provided for use by the television upon completion of the first scanning setup procedure. The method further includes automatically scanning for channels using a second scanning setup procedure at a second power mode following the first power mode. The second power mode is at a lower power mode than the first power mode, and the second scanning setup procedure is more time consuming in comparison to the first scanning setup procedure. Additional channels not detected during the initial setup by the first scanning setup procedure are automatically detected at the second power mode.

TECHNICAL FIELD

Embodiments of the present invention relate to the field of electronics.More particularly, embodiments of the present invention relate toautomatic scanning of television channels.

BACKGROUND ART

In general, television sets are setup before being used for the firsttime. For example, a television set must scan available channels beforeit can be used to display broadcast channels. Some channels may beharder to scan and to detect. Many cable and selectable providers havelong channel selections. As a result, scanning for channels may take along time, e.g., 50 minutes. Unfortunately, the television set cannot beused to display broadcast channels during the scanning period.Therefore, the longer it takes to scan for channels the longer thetelevision set remains unavailable to the user, thereby inconveniencingand potentially frustrating the new television set owner.

In general, channels cannot be added after the television set completesscanning for channels unless a new scan is performed. As describedabove, scanning for channels may take a long time, therebyinconveniencing the user by making the television set unavailable duringscanning. Therefore, many users may new channels may go undetected.

One conventional method to reduce the time required for channel scanningis to use a fast scanning method. Unfortunately, the fast scanningmethod is not a comprehensive scan of all the channels, thereby omittingmany of the channels that are harder to scan. As a result of using fastscan only a fraction of the broadcast channels are detected and becomeavailable to the user for viewing while other broadcast channels remainunavailable to the user.

SUMMARY

Accordingly, a need has arisen to enable faster channel scan to providedetected channels to the user in a timely fashion while providing anoverall scan process that is comprehensive regarding channel detection.Furthermore, a need has arisen to provide a comprehensive channel scanwhen the television is not used by the user, e.g., when in a low powermode, standby, etc., to detect channels that were missed during thefaster channel scan. Moreover, a need has arisen to automatically andperiodically provide a comprehensive channel scan to detect newly addedchannels. It will become apparent to those skilled in the art in view ofthe detailed description of the present invention that the embodimentsof the present invention remedy the above mentioned needs and providethe above referenced advantages.

According to one embodiment of the present invention, a first scanningsetup procedure and a second scanning procedure are provided. The firstscanning setup procedure is faster than the second scanning setupprocedure. The threshold timeout for the first scanning setup proceduremay be decreased during channel scan, thereby executing faster incomparison to the second scanning setup procedure. Moreover, the firstscanning setup procedure may use the modulation and the carrier standardof the first found channel to detect the remainder of the broadcastchannels. Therefore, the first scanning setup procedure executes fasterin comparison to the second scanning setup procedure. It is appreciatedthat while the second scanning setup procedure requires a longer time toexecute in comparison to the first scanning setup procedure, the secondscanning setup procedure provides a more comprehensive channel scan andmay take place while the television set is in standby mode.

More specifically, the first scanning setup procedure may beautomatically launched at the initial setup procedure, e.g., the firsttime the television set is being setup. During the first scanning setupprocedure, the television set becomes unavailable to the user. Uponrapid completion of the first scanning setup procedure, the detectedchannels become available to the user. The lengthy second scanning setupprocedure may be automatically launched when the television set isplaced in a lower power mode, e.g., standby mode, any mode of collectinginteractive program guide, power off mode, etc. In other words, the morecomprehensive channel scan is performed in the background and when thetelevision set is not used by the user.

According to one embodiment, additional channels may be detected duringthe second scanning setup procedure executed periodically. Theadditional detected channels may be channels that were missed during thefirst scanning setup procedure. The user may be prompted that newlydetected channels are ready for viewing when the television set isplaced back to its full operating mode, e.g., on mode.

Accordingly, the rapid first scanning setup procedure provides access toa limited number of detected channels in a timely fashion. The lengthysecond scanning setup procedure on the other hand detects channels thatwere missed during the first scanning setup procedure. The secondscanning setup procedure executes when the television set is not beingused. Thus, a limited number of channels are provided in a timelyfashion while a comprehensive list of channels are provided uponcompletion of the second scanning setup procedure.

It is appreciated that the second scanning setup procedure may beautomatically launched at a user defined intervals to detect newly addedchannels that are part of the broadcast channels. Similarly, the usermay be prompted and notified that new channels are detected.

More particularly a method of scanning television channels at initialsetup is provided. The method includes automatically scanning forchannels using a first scanning setup procedure at a first power mode,e.g., full power mode. During the first scanning setup procedure thetelevision is unusable by a user. Upon completion of the first scanningsetup procedure, the detected channels are automatically provided foruse by the television. The method further includes automaticallyscanning for channels using a second scanning setup procedure at asecond power mode following the first power mode. It is appreciated thatthe second power mode is at a lower power mode than the first powermode, and wherein the second scanning setup procedure is more timeconsuming in comparison to the first scanning setup procedure.

It is appreciated that the second scanning setup procedure may have alonger time out parameter for finding a channel in comparison to thefirst scanning setup procedure. The first scanning setup procedure mayuse only the carrier and the modulation used to find a first detectedchannel to detect the remaining channels while the second procedure isnot so limited. Thus, the second scanning setup procedure is morecomprehensive in comparison to the first scanning setup procedure.

The embodiments include the above and wherein the method furtherincludes while the television set is in the second power mode,automatically detecting additional channels not detected during theinitial setup by the first scanning setup procedure. The method mayfurther include, in response to detecting the additional channels,automatically providing the additional channels for use by thetelevision when the television is at the first power mode. It isappreciated that the user may be automatically prompted that theadditional channels are detected, wherein the prompting occurs at thefirst power mode.

According to one embodiment, the method may further include subsequentto automatically scanning for channels using the second scanning setupprocedure, automatically and periodically scanning for channels usingthe second scanning setup procedure at standby power mode.

A Method and System for Scanning Television Channels

Referring now to FIG. 1, an exemplary computer implemented method 100 ofa television set automatically scanning channels in accordance with oneembodiment of the present invention is shown. At step 110, a user maypower on the television set. A setup of a television set may be requiredbefore the television set can be used for the first time. For example,the television set is required to scan for broadcast channels beforeallowing the user to watch the detected channels. Accordingly, at step112, it is determined whether the television set has completed a firsttime setup such as an initial setup for channel scanning.

If it is determined that the first setup, e.g., channel scanning, hasbeen completed, then at step 160 the detected channels are automaticallyprovided for use by the user. It is appreciated that the user mayinteract with the detected channels when the television set is in a fullpower mode.

On the other hand, if the first time setup, e.g., channel scanning, hasnot been completed then no channels have been detected so at step 120, aquick scan to setup channels is automatically executed in accordancewith an embodiment of the present invention. It is appreciated that thequick scan is executed when the television set is in a full power mode.The quick scan may be a cursory scan to detect channels rapidly. Forexample, the quick scan may only take a few minutes to complete, e.g., 5minutes.

At step 130, the detected channels are stored in memory and may beautomatically provided to the user after the completion of the quickscan execution. It is appreciated that the detected channels may beprovided for use when the television set is in a full power mode, e.g.,on. Accordingly, the user may use the detected channels resulting fromthe completion of the quick scan in a short and convenient period oftime.

At step 140, a lengthy and comprehensive full scan is automaticallyexecuted when the television set is placed in a lower power mode. Forexample, when the user finishes watching television, the television setmay be placed in a lower power mode, e.g., a standby mode, etc. In otherwords, the full scan is executed when the television set is in a powermode other than its full operating mode. Accordingly, the full scan isexecuted in the background when the television set is not being used.Thus, in the lower power modes, it is of no consequence how long it maytake to execute and complete the full scan because the television set isnot being used by the user. In the full scan, detected channels areadded to the memory.

It is appreciated that the full scan is a more comprehensive scan incomparison to the quick scan. In general, scanning scans through variousmodulation standards, carrier standards and different frequencies inorder to detect a channel. Scanning may have a timeout associated withat least one of the carrier standards, modulation standards and/orfrequencies. As a result, the scanning times out and changes at leastone of: carrier standard, modulation and/or frequency when a channel isnot detected during the allotted time.

Some carrier standards, modulations and frequencies are more difficultto detect, thereby requiring a longer threshold time to be detected. Inorder to reduce the scanning time, the timeout associated with at leastone of the carrier standards, the modulation standards and/orfrequencies may be decreased during the quick scan. Reducing the timeoutassociated with at least one of carrier standards, modulation standardsand/or frequencies in the quick scan may lead to a failure to detect achannel during scanning even though that channel is being broadcast.However, reducing the timeout in the quick scan enables those detectedchannels to become available to the user in a shorter period of time incomparison to the full scan.

The comprehensive full scan may be executed in order to detect channelsthat were missed during the quick scan. This scan may take 40 minutes orlonger to complete in a typical instance. The full scan may execute inthe background when the television set is at a lower power mode. As aresult, newly detected channels that were missed by the quick scanbecome available to the user after the execution of the full scan iscompleted and when the television set is placed in a higher power mode,e.g., turned on. Thus, not only does the user have access to channelsdetected during quick scan in a short period of time resulting but acomprehensive list of channels becomes available at the completion ofthe full scan execution.

At step 142, it is automatically determined whether a new channelresulting from a full scan is detected. If the full scan detects newchannels, then at optional step 150, the user may automatically beprompted to inform the user that new channels are detected. It isappreciated that the user is prompted the next time the television setis placed in a higher power mode, e.g., turned on. At step 160, thedetected channels resulting from both the quick scan and the full scanbecome available and are automatically presented to the user when thetelevision set is in a full power mode. On the other hand, if the fullscan does not find a new channel, then at step 160, the detectedchannels resulting from the quick scan are automatically provided to theuser when the television set is in a full power mode.

It is appreciated that in one optional embodiment, at step 170, the fullscan is executed periodically when the television set is in a lowerpower mode, e.g., turned off, standby, etc. It is appreciated that thetime duration between periodic scanning using the full scan may be setduring manufacturing and/or it may be user definable. Accordingly, newchannels may be automatically detected when new channels are added andbroadcast by the service provider.

Referring now to FIG. 2, an exemplary computer controlled method 200 ofquick channel scanning in accordance with one embodiment of the presentinvention is shown. At step 210, a carrier standard may be used to scanfor channels. Carrier standards may include incrementally relatedcarrier (IRC), harmonically related carrier (HRC), standard broadcastfrequency (STD), etc.

At step 220, a modulation standard is used to scan for channels. Forexample, the modulation standard may include 8 vestigial sidebandmodulation (8VSB), quadrature amplitude modulation 64 (QAM 64), QAM 128,QAM 256, etc.

At step 222, the quick scan automatically determines whether a channelis found. If a channel is found for the carrier standard and themodulation standard, then at step 230, only the same carrier standardand the same modulation standard is used during scanning in order tofind the remaining channels. In other words, based on the first channelthat is found, the quick scan presumes that all other channels use thesame modulation standard and the same carrier standard. Scanning istherefore limited to these standards. Accordingly, the quick scan doesnot need to go through the remaining carrier standards and modulationstandards, thereby reducing the execution time.

On the other hand, if a channel is not found within a given thresholdtime period, the scanning for channels using that particular carrierstandard and modulation standard times out. It is appreciated thatreducing the threshold time is a tradeoff between the fast scan setupprocedure executing faster and detecting more channels. At step 224, itis determined whether all the modulation standards have been used. Ifall the modulation standards have not been used, at step 240, themodulation standard is changed. As a result, at step 220, the samecarrier standard is used with a new modulation standard to scan and todetect a channel.

At step 224, if it is determined that all the modulation standards havebeen used, at step 250, the carrier standard is changed to a nextcarrier standard. As a result, at step 210, a new carrier standard isused to scan and to detect a channel. Accordingly, the process forfinding a channel may be repeated until a channel is found.

It is appreciated that other embodiments may repeat the process withoutusing the modulation standard and the carrier standard for the firstchannel that is found. For example, the exemplary method 200 may berepeated without step 230. As such, a predetermined number of channels,e.g., 10 channels, may be detected. Thereafter, statistical analysis maybe performed on the carrier standard and the modulation of each of thedetected channels in order to determine the carrier standard and themodulation standard to be used to detect the remainder of the channels.In other words, a statistical analysis of a few channels that have beenfound may be used to determine the appropriate modulation standard andthe appropriate carrier standard to be used to detect the remainingchannels. As a result, the statistical analysis leads to detection ofmaximum number of channels during the quick scan period.

It is appreciated that in one embodiment, the execution time of the fastscan may be further reduced by reducing of the threshold time causingthe scanning to timeout when a channel is not found for a given carrierstandard and a given modulation standard. As a result, the execution ofthe quick scan setup procedure may be completed in less time than thefull scan setup procedure. It is further appreciated that the executiontime for quick scan may be further reduced by reducing or removingchannel tuning. Moreover, the execution time for the quick scan setupprocedure may be further reduced by eliminating the decoding todetermine whether a found channel is scrambled.

Accordingly, the use of the quick scan and the full scan strikes abalance between the number of channels provided and the amount of timeit takes to provide those channels to the user. For example, oneembodiment may provide a limited number of channels in a very shortamount of time while providing a more comprehensive list of channelsafter the completion of the full scan execution.
